Is B a bad grade in the US?

Anonymous
In my country the grade system in education is:

12 = A
10 = B
7 = C
4 = D
2 = F
00
- 3
You pass when you get minimum 2/F. 7/C is a good average grade and 10/B and 12/A are both considered really good grades. So why is B’s viewed as bad in the US. I don’t know if it is true, it just always sounds like that.
